RELL1 and diabetes mellitus: It is notable that the signals for persistent carriage of S. aureus appear to be largely independent of signals for intermittent carriage of S. aureus. Of all top findings, only rs61440199 (KAT2B) and rs16993852 (RELL1) show nominal evidence of association in both persistent and intermittent carriage of S. aureus. Diabetes stratified and non-stratified analyses of both persistent and intermittent carriage gave highly concordant results across all analyses (Figs M-N in S1 File).
